You choose the sum yourself. The small sum (€2,00 EUR) is perfectly fine for a subscription, but if you plan to unsubscribe immedately after downloading, please pay one of the larger amounts instead (at least €10,00 EUR).

After subscribing, you will immediately get access to the full versions of Radium for Linux, Mac OS X, and Windows.

About the subscription model

You subcribe to get download/upgrade access and to get support, not to be able to use the program. Binaries you have downloaded will continue to work also after the subscription runs out. Furthermore, you don't need to be connected to the internet to use the program, and there is no keyfile or anything else that identifies you with the program. The program has no copy protection.

Feature requests from medium sum subscribers will be prioritized higher than small sum subsribers, and feature requests from large sum subscribers will be prioritized higher than medium sum subscribers.
Feature requests from non-subscribers will be ignored, except for very good ideas.

Source code

Information to warez groups
Since the source is open, it should be simple to turn the demo into a fully featured version.
Please let me know of any problems. (Just compiling the source is cheating!)

1Does not contain the Faust Development instrument (same with the full version)2Does not contain the Pure Data instrument (same with the full version)3Latest version requires OSX 10.10 or newer. Radium 5.3.3 and older requires OSX 10.8 or newer. 1) Running Radium on MacOS High Sierra (10.13) works on some computers, but there have been reports of crashes and strange graphics, probably related to OpenGL (10.13.2 and earlier). Hopefully this will be fixed in future updates from Apple. 2) MacOS Sierra (10.12) seem to only have some minor problems left now, graphical artifacts, strange GUI behaviors, and so forth, but it should be usable. 3) MacOS El Capitan (10.11) now seems to work perfectly, but hasn't been tested as much as 10.12. 4) Older versions of MacOS should be fine.4Radium is compiled under Fedora 17 / glibc 2.15, using GCC 7.2.0. It is also tested under Fedora 20 and Fedora 22. It was earlier tested under Ubuntu 14 as well. Other distributions might not work. You should normally be fine though, especially if you don't use Ubuntu or a Ubuntu derivative such as Mint, since Ubuntu tends to do things differently than other distributions.5The Linux binares does not include the Faust Development instrument since it's difficult to make LLVM binaries work across distributions. In case you want the Faust Development instrument, you should compile Radium manually.

Is there a feature you really want? Perhaps audio multitrack editing, or LV2 plugins?
Or maybe you have an idea you want to see realized? Then support the development of Radium.

You can also help Radium get a steady progress by subscribing. Bug reports and feature requests from subscribers are prioritized.
